Homemade gluten-free play dough
with neon food coloring
Dot pages from DLTK
(I got the 'H' for Harper here.)
You can buy the really nice, expensive dot markers, or you can buy the plain old bingo markers from Dollar Tree. If you go the cheaper route, be warned: they can stain and get messy.
Pick a color for each week and do a different activity each day.
I put a piece of matching cardstock on the back of each card before laminating them. She really liked these.
Chopsticks, pom-poms, and a muffin tray.
(Ok, maybe not hours, but quite a few minutes.)
I can now say that my child is not color blind. We were concerned for a while, but with a little play time and some time to let it all rest (that was the key), she is now a color recognition pro.
